I note that the reverse situation does not result in the same problem. If I log in and then log out, kwin_x11 does not hang. The main difference between him and me is that I am a sudoer and he is not (he is 6 years old!) and I have configured my plasma (for example to use the classic K menu) while his is more or less what is out of the box.
** Attachment added: "logged in as mgolden, there is a kwin_x11 still running as user dario.
